Speechmatics

Speechmatics is a speech recognition company that offers highly accurate speech-to-text through an API. It transcribes audio in real time or in batches across more than 50 languages, and is known for handling a wide range of accents and dialects well.

Beyond transcription, Speechmatics provides translation, speaker diarisation, punctuation and formatting, and tools for building voice agents that need to understand speech instantly. It can be used in the cloud or deployed on-premises for organisations with strict data requirements. Media companies, contact centres and software vendors build it into captioning, monitoring and voice products.

Good fit if you: are building a product that needs accurate, multilingual speech-to-text through an API, in the cloud or on your own servers.
Less ideal if you: just want to transcribe a few files yourself; an end-user transcription app is simpler.

Pricing: usage-based with a free monthly allowance to get started; enterprise and on-premises options are available.
